Title: Improvements in drip-feed dispensing devices
IPC: B01J4/02
Filed: 1954-11-05
Abstract: 817,387. Regulating fluid flow. FLETCHER, R. L., LANDI, M., BURR, H. C., POCOCK, A. G., and KIRK, C. R. Nov. 1, 1955 [Nov. 5, 1954; Oct. 18, 1955], Nos. 32110/54 and 29745/55. Class 135. Construction.-The reservoir 1, Fig. 1, is open to the vessel 2 by a connector 3 embodying large and small diameter bores 6, 7 respectively, whilst a bore 8 leading to a pipe 9 puts the vessel 2 in communication with atmosphere; the bores 6, 7 and 8 open into the reservoir 1 and/or vessel 2 at different levels, as shown, through orifices 6a, 6b, 7a, 7b and 8a. A dispensing faucet 10, which depends from the vessel 2, comprises a plug 13, Fig. 2, that passes through the base of the vessel and incorporates axial and radial bores 13a, 13b which open into the coned base 19b of a body 19 threaded on to the plug 13. The base 19b leads to a handcontrolled screw 15 with blunted thread crests via a restricted bore 19c and leaves the screw by an axial bore 16 that opens into a cup 18 having a nozzle 18a; an air vent 17 is provided in the cup 18. The reservoir 1, plug 13, screw 15, body 19 and cup 18 are made of transparent thermo-plastic material. Operation.-The cap 1a of the reservoir 1 is removed and the latter is filled with liquid, such as sodium hypochlorite; the vessel 2 also fills up and liquid rises in the pipe 9 to the same level as that in the reservoir 1; the cap is then replaced to effect an air-tight seal. When the faucet 10 is opened liquid drips therefrom at a rate determined by the setting of the screw 15 relative to the bore 16. Liquid from the reservoir 1 replaces that draining from the vessel 2, but since the reservoir 1 is sealed from atmosphere a partial vacuum is created therein as liquid level falls, until a balanced pressure point is reached whereupon liquid ceases to flow from the reservoir 1 but since the vessel 2 is open to atmosphere through the pipe 9 the liquid in the latter flows into the vessel 2. The liquid level in the vessel 2 continues to fall until the orifice 7a is uncovered so that air from above the liquid in the vessel 2 enters the reservoir 1 producing an increase in the air pressure therein and enabling more liquid to flow into the vessel 2 through the bore 6 until the orifice 7a is covered whereupon transference of air between the containers again ceases. This interchange of liquid and air between the containers recurs at intervals and since the difference in level between orifices 6a and 7a may be small the head of liquid in the vessel 2 is kept substantially constant.

Abstract: 1,194,732. Bromites. SOC. D. ETUDES CHIMIQUES POUR L'INDUSTRIE. 12 July, 1967 [22 July, 1966; 16 May, 1967; 22 May, 1967], No. 32142/67. Heading C1A. Calcium bromite is prepared by mixing bromine and hydrated lime in an aqueous medium at below 20 C. The rates of addition are controlled so that the pH does not fall below 10, and so that, before the quantity of calcium bromide present reaches 20% by weight and up to the end of the mixing, the proportions of bromine and hydrated lime are kept close to the stoichiometric, that is 1 mole Br 2  to 1 mole Ca(OH) 2 . When the total quantity of reactants has been added the pH is adjusted to between 9À3 and 10À5, and the mixture stirred until the quantity of hypobromite remaining in the mixture represents less than 15% of the total oxidizing power. The solid precipitate containing calcium bromite is then separated from the mother liquor. The weight ratio of Ca(OH) 2  to water of the reaction medium is between 30 and 40% and does not exceed 45%. Alkali metal bromides may be prepared from the calcium bromide obtained in the process by submitting the solid product together with an alkali metal carbonate, sulphate or hydroxide to double decomposition.

Title: Temperature control system

Filed: 1960-09-20
Abstract: 965,229. Temperature responsive actuating elements. ALCO VALVE CO. Sept. 20, 1960 [Nov. 30, 1959], No. 32263/60. Heading G1D. A temperature control system,for example, for controlling the flow rate of refrigerant through the evaporator of a refrigerator plant according to the temperature of the refrigerant as it leaves the evaporator, employs a temperature sensing bulb 10 connected by a capillary tube 11 to a chamber 12 having means such as a diaphragm which is responsive to pressure changes in the chamber and which is connected to a flow controlling valve &c. so that the valve setting depends on the chamber pressure which in turn depends on the bulb temperature,the volume of the bulb being greater,for example,three times as great, as the combined volume of the chamber and tube and the control system being charged with a mixture of condensible and non-condensible fluids proportioned so that a quantity of volatile liquid is maintained in the bulb even when the temperature of the chamber is below that of the bulb, whereby the temperature at the bulb location acts as the sole controlling factor, remaining unaffected by the temperature at the chamber location. The system is charged through an opening 13 at a temperature higher than that at which it will operate. Firstly, the vapour of a volatile liquid such as a refrigerant is infected until the system pressure is two-thirds or threequarters of the final pressure which is attained by then infecting a non-condensible gas such as nitrogen. Thus the volatile may be charged to bring the pressure to 80 1b per sq. inch and the nitrogen added to bring the pressure to its final value of 105 1b per sq. inch. When put into use, some of the vapour condenses in the bulb and chamber and thereafter, due to the proportioning of the volatilenitrogen charge, the pressure in the chamber varies according to bulb temperature independently of temperature changes at the chamber location.
